MacPAR deLuxe is a utility program that runs on the Apple Macintosh. It
is useful to you if you download (or upload) binary files from internet
newsgroups (a.k.a. "Usenet").
Often, binary content comes in the form of sets of many files that
together form a "rar" archive. MacPAR deLuxe assist you in combining
these files after the download finishes.
- It verifies that the file set is complete, and all files are undamaged.
MacPAR deLuxe can recover missing information by processing so called
"par" and "par2" files.
- After the verification step, MacPAR deLuxe unpacks the data. If
possible with its built-in unrar engine, or otherwise by launching the
appropriate program.

MacSOUP is an offline reader for Usenet newsgroups and Internet e-mail.
If you don't know what newsgroups are, you probably don't need this
program. MacSOUP is primarily a newsreader, its e-mail capabilities are
somewhat rudimentary compared to "real" e-mail clients.
If you need a newsreader for the orignial intent of Usenet, this is the newsreader for you.

NZB Drop frees you from crawling through millions of headers to get at the content you
want. With an NZB file specifying your desired content, simply drag and drop unto NZB Drop
and experience the simplest, drop dead fastest way ever to retrieve files from Usenet
newsgroups.

The small and efficient NZB client for OSX, optimized for performance
and ease of use. NZBVortex is very feature complete and extremely tuned
for optimal download speeds and minimal system resource usage. Just
search for or add your desired NZB then let take NZBvortex control: it
will download the minimal required data to complete the download,
uncompress, cleanup and move the download to your desired location. No
overflood in settings or info: we take care of all the technical stuff
in the background. A real set-and-forget download application: add a NZB
and NZBVortex will take care of the rest.

RAR is a compression and decompression program that allows you to save files, password protect them, or even take large files and break them up into many smaller parts.
RAR is available for several platforms, and you can even download the decompression part for free.

1. What is this
This is a very simple interface to the rar binary. And RAR is a popular
compression format in the PC-side-of-the-life. Keep in mind that the RAR
format won't support OSX-specific flags (ie, resource fork). For
advanced options, use the rar binary in CLI mode itself, or look for
other interfaces.
2. Usage
Use the Preferences window to adjust some settings (password if needed,
segments if needed, etc.) and then drop onto Rarify's icon your
file(s)/folder(s) in order to compress them.
3. Requirements & Installation
Rarify will run under OS X 10.4 and 10.5, both Intel and PPC architectures.
1. Drop Rarify onto your favorite location.
Due to licensing issues, I prefer you install the rar binary manually
yourself (so you can read its readme, read its license, purchase a copy
or whatever you wish).
2. Install if needed the rar binary. To do so:
-Go to http://www.rarlabs.com/ downloads section.
-Choose your favorite download (usually, the newer version of the rar binary for OS X) and download it.
-Unpack.
-Make a new Finder window ("Apple + N"). Type "Apple + Shift + G". Type "/usr/local/bin".
-Now, copy the unpacked "rar" binary file onto the "/usr/local/bin" window. Authenticate as administrator if needed.
If you prefer not doing such a thing (!), you can copy as well the rar binary to the following destination (instead of "/usr/bin" or "/usr/local/bin"):
-Rarify/Contents/Resources..
3. You can instead use the "Update RAR binary..." menu item under the
application menu and these steps will be done automagically by Rarify.

SABnzbd is an Open Source Binary Newsreader written in Python.
It's totally free, incredibly easy to use, and works practically everywhere.
SABnzbd makes Usenet as simple and streamlined as possible by automating
everything we can. All you have to do is add an .nzb. SABnzbd takes over
from there, where it will be automatically downloaded, verified,
repaired, extracted and filed away with zero human interaction.

The Unarchiver is a much more capable replacement for
"BOMArchiveHelper.app", the built-in archive unpacker program in Mac OS
X. The Unarchiver is designed to handle many more formats than
BOMArchiveHelper, and to better fit in with the design of the Finder. It
can also handle filenames in foreign character sets, created with
non-English versions of other operating systems. I personally find it
useful for opening Japanese archives, but it should handle many other
languages just as well.
Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip,
LhA, StuffIt and many other more or less obscure formats.
